Abstract: Apparatus for removing at least a part of a thermal sprayed wear resistant coating on a gas turbine engine part includes a a superabrasive grinding wheel (22) which includes a superabrasive material comprising at least one of cubic boron nitride and diamond. The apparatus further includes a rotating device capable of rotating the superabrasive grinding wheel at a rate of at least 3,000 revolutions per minute and a supporting device (26) configured to support the gas turbine engine part (10) and creep feed the gas turbine engine part (10) into contact with the super abrasive grinding wheel (22) so that the super abrasive grinding wheel (22) is configured to remove the thermal sprayed wear resistant coating (12) at a peripheral speed of about 8,000 to about 10,000 surface feet per minute (2,440 to 3,048 meters per minute).
